Critical stages in the individual development of introduced plants

Blog Article

The historical aspects of studying the stages of individual plant development are considered.The regularities of the change in the stages of ontogeny are discussed.Their different degree of selectivity and sensitivity to certain environmental factors (environmental signals) in different periods of ontogenesis is shown.

Concepts of critical periods in the ontogenesis of plants characterized by a decrease in their stability at this stage of development and oppression Bosch DWK98PR60B Serie 8 Built In 89cm 3 Speeds A+ Chimney Cooker Hood Black or lack of regenerative processes in the body are analyzed.The role of P.G.

Svetlov as the founder of this trend in science is emphasized.The scheme of formation of critical states in the process of plant development from the positions of combined (total) action of environmental factors is shown.Ideas of spasmodic spiral development of organisms with its transient (revolutionary) and smooth long (evolutionary) stages are discussed.

Inter- stage transient periods of ontogeny are considered as the most vulnerable in the life of organisms, which is explained by the large expenditure of energy during the formation of new structures and, as a consequence, the decrease in their stability.Examples of critical Wine Bottle Holder periods in plant ontogeny are given.The described regularities of the change in the stages of ontogeny are explained by provisions of the information-energy theory of the development of organisms.
